Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, and in particular to a vibration-damping wheel hub outer circle cutting processing device. Background Technology

[0002] As a core load-bearing component of automobiles, construction machinery, and other equipment, the machining accuracy of the outer circle of the wheel hub directly affects the driving stability, safety, and service life of the equipment.

[0003] During the machining of the outer diameter of a wheel hub, factors such as the cutting force of the CNC machine tool, the centrifugal force generated by high-speed rotation, and the vibration of the equipment during operation can easily lead to vibration during the machining process.

[0004] Vibrations generated during processing are directly transmitted to the worktable and stationary table. Most existing devices do not have effective buffer and vibration reduction mechanisms, or only use a single spring buffer structure, which has limited vibration reduction effect. Vibrations will not only aggravate tool wear and reduce processing efficiency, but also further affect processing accuracy, resulting in a low finished product qualification rate.

[0005] Therefore, a vibration-damping wheel hub outer diameter cutting device is needed to solve the above problems. Utility Model Content

[0006] The main purpose of this utility model is to provide a vibration-damping wheel hub outer diameter cutting device, which can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vibration-damping wheel hub outer diameter cutting device includes a CNC machine tool and a worktable installed on the inner side. The worktable has a mounting groove in the middle, and a fixed platform is provided in the mounting groove. Three dampers connected to the lower part of the fixed platform are arranged in a ring around the outer circumference of the bottom wall of the mounting groove. Three buffer components connected to the lower part of the fixed platform are arranged in a ring around the inner circumference of the bottom wall of the mounting groove. A fixing component for fixing the wheel hub is provided together between the upper part of the fixed platform and the bottom wall of the mounting groove.

[0008] Preferably, the fixing assembly includes an electric telescopic cylinder installed on the bottom wall of the mounting groove. The piston rod of the electric telescopic cylinder is provided with an annular sleeve. A connecting plate is provided on the upper part of the annular sleeve. Clamping rods are provided on the upper triangular part of the connecting plate. A spiral groove is opened on the lower part of the outer surface of each of the three clamping rods. A guide sleeve installed on the lower part of the lower part of the outer surface of each of the three clamping rods is provided. A protrusion is provided in the middle of the inner surface of each of the three guide sleeves.

[0009] Preferably, the upper parts of all three clamping rods pass through the upper part of the fixed platform.

[0010] Preferably, all three protrusions are movable within a spiral groove located on the same side.

[0011] Preferably, the buffer assembly includes a support base installed on the bottom wall of the mounting groove. The upper part of the support base and the lower part of the fixed platform are both provided with mounting plates. The two mounting plates are respectively provided with a transmission rod one and a transmission rod two on their opposite sides.

[0012] Preferably, the two transmission rods and the buffer spring are symmetrically distributed vertically.

[0013] Preferably, an arc-shaped block is provided between the transmission rod 2 and the transmission rod 1 located on the same side, and a cylindrical rod is provided between the two arc-shaped blocks. A limiting plate is provided in the middle of the outer surface of the cylindrical rod, and buffer springs are provided on both vertical surfaces of the limiting plate and the opposite surfaces of the two arc-shaped blocks.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model forms a dual vibration reduction structure through the design of a damper and a buffer assembly. During the processing, when the cutting force, centrifugal force and vibration generated by the operation of the equipment are transmitted to the fixed table, the damper can quickly attenuate the vibration energy, and the buffer assembly further absorbs the vibration impact force through the synergistic effect of the transmission rod, the arc block and the buffer spring, reducing the impact of vibration on the processing process. This not only reduces tool wear and improves processing efficiency, but also avoids the deviation in processing accuracy caused by vibration, and greatly improves the qualification rate of the finished wheel hub.

[0015] 2. This utility model uses an electric telescopic cylinder to drive the clamping rod to move up and down. With the cooperation of the protrusion inside the guide sleeve and the spiral groove, the clamping rod completes the vertical to horizontal posture conversion during the movement, and is tightly attached to the wheel hub for fixation. This avoids displacement or additional vibration of the wheel hub due to insecure fixation during the processing, and further ensures the processing accuracy. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1 and Figure 2 As shown, a vibration-damping wheel hub outer diameter cutting processing device includes a CNC machine tool 1 and a worktable 2 installed in the middle of the inner side. The worktable 2 has an installation groove in the middle, and a fixed platform 3 is provided in the installation groove. Three dampers 4 connected to the lower part of the fixed platform 3 are arranged in a ring around the outer ring of the bottom wall of the installation groove. Three buffer components 5 connected to the lower part of the fixed platform 3 are arranged in a ring around the inner ring of the bottom wall of the installation groove. A fixing component 6 for fixing the wheel hub is provided together between the upper part of the fixed platform 3 and the bottom wall of the installation groove.

[0020] This device is mainly used to process wheel hubs with large gaps between their surfaces.

[0021] The cutting operation of this device is performed by a CNC machine tool 1, which adopts the existing technology model XH850-CNC. The worktable 2 is installed inside the CNC machine tool 1. The specific installation method is conventional technology for those skilled in the art and will not be described in detail here.

[0022] The specific workflow of this device is as follows: The operator first turns on the CNC machine tool 1, then places the wheel hub on the upper part of the fixed table 3, passes the wheel hub through the fixed component 6, and adjusts the center position. Then the operator starts the fixed component 6 to fix the wheel hub on the fixed table 3. Finally, the CNC machine tool 1 is started to process the wheel hub placed on the fixed table 3.

[0023] In the above process, vibration is generated when the wheel hub is processed, and the vibration is transmitted to the fixed platform 3. At this time, the vibration received by the fixed platform 3 is buffered by the damper 4 and the buffer assembly 5, thus achieving vibration prevention.

[0024] In the above-mentioned process, the fixed platform 3 and the worktable 2 need to be sealed during implementation to prevent coolant from flowing into the mounting groove of the worktable 2 when the wheel hub is being processed.

[0025] In Example 2, further, in order to achieve the purpose of fixing the wheel hub with the fixing component 6, see [reference needed]. Figure 3 , Figure 4 and Figure 5 The fixing component 6 includes an electric telescopic cylinder 64 installed on the bottom wall of the mounting groove. The piston rod of the electric telescopic cylinder 64 is provided with an annular sleeve 67. The upper part of the annular sleeve 67 is provided with a connecting plate 62. The upper triangle of the connecting plate 62 is provided with clamping rods 61. The lower part of the outer surface of the three clamping rods 61 is provided with a spiral groove 65. The lower part of the outer surface of the three clamping rods 61 is provided with a guide sleeve 63 installed on the lower part of the fixing platform 3. The middle of the inner surface of the three guide sleeves 63 is provided with a protrusion 66. Furthermore, the upper parts of all three clamping rods 61 pass through the upper part of the fixed platform 3; Furthermore, all three protrusions 66 are movable within the spiral grooves 65 located on the same side.

[0026] The workflow of fixed component 6 is as follows: The hole made in the wheel hub plane lock passes through the three clamping rods 61, and the wheel hub is placed on the upper part of the fixed platform 3. The wheel hub is transported by the mechanical arm clamping and transporting, so that when the mechanical arm places the wheel hub on the fixed platform 3, it can be placed in the middle state.

[0027] Then, the staff controls the electric telescopic cylinder 64 to work, causing the piston rod of the electric telescopic cylinder 64 to retract, and drive the connecting plate 62 to move downward through the annular sleeve 67. At this time, the connecting plate 62 will drive the three clamping rods 61 to move downward and slide inside the fixed platform 3.

[0028] In the above description, the clamping rod 61 is rotatably mounted on the connecting plate 62. When the clamping rod 61 moves down, it slides in the inner cavity of the guide sleeve 63 and causes the protrusion 66 to slide in the inner cavity of the spiral groove 65. Under the action of the spiral groove 65 and the protrusion 66, the clamping rod 61 rotates when it moves down. At this time, the upper part of the clamping rod 61 will rotate from a vertical state to a horizontal state, so that when the clamping rod 61 moves down, it cannot pass through the wheel hub gap and can only contact the wheel hub, thus achieving the purpose of fixing the wheel hub on the upper part of the fixing platform 3.

[0029] In the above, when it is necessary to release the wheel hub, the piston rod of the electric telescopic cylinder 64 extends again, pushing the connecting plate 62 to move upward. At this time, the clamping rod 61 will rotate from the horizontal state to the vertical state under the action of the spiral groove 65 and the protrusion 66, thus releasing the wheel hub.

[0030] Furthermore, in order to achieve the purpose of vibration damping of the wheel hub placed on the fixed platform 3 through the buffer assembly 5 and the damper 4, refer to Figure 6The buffer assembly 5 includes a support base 51 installed on the bottom wall of the mounting groove. The upper part of the support base 51 and the lower part of the fixed platform 3 are both provided with mounting plates 52. The two mounting plates 52 are respectively provided with transmission rod 1 53 and transmission rod 2 57 on opposite sides. Furthermore, the two transmission rods 57 and the buffer spring 56 are symmetrically distributed vertically; Furthermore, an arc-shaped block 58 is provided between the transmission rod 2 57 and the transmission rod 1 53 on the same side, and a cylindrical rod 54 is provided between the two arc-shaped blocks 58. A limiting plate 55 is provided in the middle of the outer surface of the cylindrical rod 54, and buffer springs 56 are provided on both vertical surfaces of the limiting plate 55 and the opposite surfaces of the two arc-shaped blocks 58.

[0031] In the above, the fixed platform 3 is supported by three dampers 4.

[0032] The movement process of buffer component 5 is as follows: When the fixed platform 3 vibrates, the resulting impact is transmitted to the upper mounting plate 52 and the damper 4. At this time, the upper limit plate 55 will move downward slightly. The purpose of the transmission rod 57 rotating between the mounting plate 52 and the arc block 58 is to make the upper mounting plate 52 move downward, which will drive the transmission rod 57 to rotate and slide on the outer surface of the cylindrical rod 54 through the arc block 58. When the arc-shaped block 58 slides, it pulls the transmission rod 53 to rotate together, and squeezes the buffer spring 56 through the limit plate 55, so that the buffer spring 56 absorbs the impact force generated by the vibration and performs buffering.

[0033] As described above, the combined action of the buffer spring 56 and the damper 4 can reduce the vibration generated on the fixed platform 3, achieve the effect of vibration prevention, and reduce the impact of vibration on the wheel hub processing.

[0034] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic cylinder 64 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
